AUTOMOBILE HEADLIGHT.

Application filed August 14,1922.

To all whom. it may concern:

Be it known that I, SANDER I. CHRISTEN- SEN, a citizen of Denmark, residing at Willows, in the county of Glenn, State of California, have invented a new and useful Au-- it is very diflicult to prevent drivers ap preaching an automobile from being so blinded by the head lights as to interfere with them and make accidents likely to happen With the present invention a reflector is used, which is provided with a silvered surface adapted to scatter the light sulficient ly to illuminate the road on all sides, but which reflector is provided with a dull reflecting surface at the center to prevent approaching drivers from being blinded.

Other objects of the invention will appear as the description proceeds.

An embodiment of the invention is shown in the accompanying drawings in which the same reference numeral is applied to the same portion throughout.

Fig. l is a side elevation partly in section of the complete lamp.

Fig. 2 is a back View of the lamp showing the manner of supporting it and showing the means for securing the reflector and reflector cover in place.

Fig. 3 is a front elevation of the reflectorc Fig. d is a plan View of the ring for retaining the reflector and glass cover in place.

Fig. is a view of one form of the reflector in which the upper portion of the lamp is provided with a smaller amount of mirror surface than is shown in Figure 3, the object being to break up the rays of light from the upper portion of the reflector more than the reflector in Figure 3 will do.

Figure 6 is a view, partly in section of a form of the lamp in which the light globe is carried by the glass cover.

Serial No. 581,573c

The reflector consists of a suitable body of metal or glass convex outwardly as indicated at 1, which has a socket 2 placed at its center to carry the ordinary electric globe 3. This reflector is supported-by a fiat plate 4:, said flat plate having two'supporting ears 5 and 6 to connect it to the ordinary lamp supporting yokes, in a manner well known in the art. The plate 4 has pins 7 and 8 which are for the purpose of securing the cover retaining ring 9 in place. This ringhas bayonet joined slots 10 on. opposite sides thereof with which the pins 7 and 8 are engaged to secure said ring in place. 7

The retaining. ring bears upon a head 11 on the outer rim of the semi-spherical glass coverLQ, said cover also bearing upon the outer periphery of the reflector 1, and thereby holding it in place.

It will be seen in observing Figures 3 to 5 that the lower portion of the reflector is silvered and the upper portion is silvered over only a portion of its, upper area, the center of said reflector being painted with a dull enamel such as aluminum paint or something of that character, to reflect the light without causing the formation of blinding rays, such as are reflected from the ordinary silvered surface.

l/Vhere less light is desired to be reflected from the upper portion of the reflector, lines or a Word orletters covering a portion. only of the reflector may be silvered as indicated at the upper portion of Figure 5, the lower portion of the reflector being also silvered, and the central portion being covered with a dimly reflecting enamel. D

While the lamp has been shown in Figures l to 5' as being carried by the reflector itself, it is equally possible to secure the lamp to the glass cover as indicated in Figure 6.

In this figure the lamp back is indicated at 20, the convex reflector at 21, which reflector is silvered in substantially the same manner as the reflector shown in Figure 3; the semi-spherical glass cover 22 is secured in place by means of a ring 23 in substantially the same manner as the ring 9 is secured to the pins 7 and 8, pins 2t, 25 being used for this purpose. At the front of the semi-spherical cover it has a lamp socket, in which is placed the lamp 2?.

In operation it will be seen that the light from the lamp, in either form of the invention, will strike the convex reflector in such a manner as to be reflected downwardly upon the road, substantially none of it from the lower portion of the reflector being reflected' into the eyes of the on-coming driver. Whatever strikes the upper portion of the reflector will be reflected onto the sides of the road, or above the view of the approaching driver 50 as to not interfere with him in any degree.

What I claim is a follows, but various modifications may be made in the construction shown in the drawings and above particularly described form, within the pur- 16 view of my invention.

SANDER I. CHRISTENSEN.
